Upgraded September 2013 to include (2) drop in Solenoid Regulator valve assemblies, TCC Boost valve assembly, Pressure Regulator Boost valve assembly and parts for renewing Pressure Control Solenoids. Convenient drop in valves!
Addresses Rough shifts, Bump-Bump downshifts above 30 mph hot and Part throttle downshift bang; Flares during up-shifts & kick-down, rough coast downshifts, No pressure rise, TCC slip/shudder and overall Poor shift quality. Improves and restores correct drivability with added durability.
Good news! No need to buy a $1200 Valve Body to FIX these complaints.
Installation recommendation: Experienced technician Transmission removal necessary: No
Starting in 2007 the Aisen series transmissions used in VW/Porsche changed the diameter of the electrical solenoids. The only way to know for sure if the kit will work is to remove the transmission oil pan and measure the OD of the solenoids. If the OD (outside diameter) is 1" the kit will work/fit.
